Product Overview
The Intel® NetStructure™ ZT 8101 10/100 Ethernet switch is a managed Ethernet switch fabric
board, which is designed to fit in a 6U, CompactPCI* form factor and which conforms to the
PICMG* 2.16 specifications.
The ZT 8101 switch is a 24-port 100Mbps Ethernet switch with two GbE. There are two GbE and
two 10/100Mbps uplink ports on the front panel. Twenty-two 10/100Mbps Ethernet ports are
routed to the backplane to provide connections to 19 node slots, two CMM slots, and a redundant
switch slot. The printed circuit board dimension is 233 mm (H) x 160 mm (D).
The diagram below shows that two switches can be connected over the backplane to node slots in a
dual star configuration as specified in PICMG 2.16.

After the system boots, the first program executed is the PROM loader. The PROM loader
performs the following tasks:
• Runs system memory diagnostics.
• Decompresses RUNTIME from FLASH to system memory for execution.
• Upgrades firmware. Users can upgrade RUNTIME using the Zmodem protocol through the
RS-232 port. For instructions, see See “Firmware Upgrade” on page 41.

The ZT 8101 switch has three methods for configuring switch parameters and viewing switch
status and statistics.
3.1
Serial Port
The switch has a serial port on the front panel to which you can attach a terminal or PC running
terminal emulation software such as HyperTerminal. The default settings for this serial port are:
•
•
•
•
•
9600 bps
Non-Parity
8 data bits
One stop bit
Flow control off
You can configure the following values:
• Baud Rate: Possible baud-rate values are 9600, 38400, 115200.
• Idle Timeout: You can specify an idle timeout value, so that the system automatically
terminates a user’s session after a period of inactivity. Options are Never, 2 minutes, 5
minutes, 10 minutes, and 15 minutes. Never prevents a session from being terminated for
idleness.
Note:
The other options (flow control, parity, data bits, and stop bits) are not currently configurable.
The serial port requires a cable with a DB-9 terminal adapter and RJ-45 adapter. You can use the
Cisco cable kit (Order Number: ACS-DSBUASYN) or make your own. See Appendix G, “Serial
Port Requirements” for specifications.
The default user account has empty strings for user name and password. As soon as you create a
user, you are prompted to log in as that user and the default account is no longer accessible.
3.2
Telnet Console
The switch’s embedded Telnet server allows users from remote systems, which are running a
Telnet application over TCP/IP, to log in to the switch, configure it, and view the status of and
statistics from the ports. The current implementation allows eight Telnet sessions to be active at the
same time.
The Telnet Console interface has the same look and feel as the interface for the serial port.

3.3
Web Console
The switch’s embedded Web server allows users from remote systems, which are running a Web
browser, to log in to the switch, configure it, and view the status of and statistics from the ports.
The current implementation allows 5 HTTP sessions to be active at the same time.

Layer 2 Switch Features
This section describes the Layer 2 features that the switch supports.
4.1
Ethernet Port Configurations
4.1.1
Auto-Negotiation and Force Mode
By default, the switch is configured to use auto-negotiation to determine each port’s speed and
duplex setting. The user can modify this and configure a port to use a specified configuration. The
Ethernet ports have the following characteristics:

Gigabit Ethernet

Flow Control
All ports have a traffic limit because they have a limited buffer space to receive incoming frames.
Upon reaching the limit, a port either starts dropping packets or triggers flow control. The ZT 8101
switch uses the following methods for flow control:
• 802.3x flow control: The switch sends PAUSE frames which request remote ports to delay
sending packets for a period of time. Sending ports suspend further frame transmission until
the specified time period has elapsed.
• 802.3x compliant flow control: The switch does not send PAUSE frames, but it does respond
to them.
• Back pressure: The switch fakes a collision and then transmits a jam sequence to ensure all
stations are notified of the “collision.” This causes the sending ports to trigger their back-off
routines and reduces the amount of traffic on the port.
The port type and duplex mode determine which type of flow control is used. The following table
lists the port types and their flow control methods.

By default, flow control is off. If you enable it, it may affect the multicast forwarding rate and
packet priority scheduling.
Port Security and MAC Address Learning
For security purposes, you can disable MAC address learning on one or more ports. When MAC
address learning is disabled, a port uses the first packet received as a permanent address and
accepts broadcast traffic and packets only for that one MAC address. New addresses are not
learned.
The default value for each port is learning enabled.
4.2
Port Mirroring
Port mirroring allows the traffic on a particular port to be monitored by sending copies of the
packets to a target port. You can then attach a logic analyzer or a RMON probe to the target port
and study the traffic crossing the source port in a completely unobtrusive manner. You can
configure only one port to be a target port, but you can select multiple ports to be mirrored to this
target port.
You can select which traffic is mirrored. For a given mirrored port (or source port), you can select
to mirror only incoming traffic, only outgoing traffic, or both.
When mirroring ports, remember the following:
• For optimum performance, you should mirror three or fewer ports at any given time.
• The target port should be operating at the same or higher speed than the source port. If the
target port is operating at a lower speed than the source port, packets will be lost.

Layer 2 Switch Features
4.3
Filtering
A filtering database is used to segment the network and control communication between segments.
It can also filter packets off the network for intrusion control.
Each port on the switch is a unique collision domain, and the switch filters (discards) packets
whose destination lies on the same port as where it originated. This keeps local packets from
disrupting communications on other parts of the network.
The switch does some filtering automatically:
• Dynamic filtering - The switch automatically learns and ages MAC addresses and their
location on the network. Filtering occurs to keep local traffic confined to its segment.
• Filtering done by the Spanning Tree Protocol - STP filters packets based on topology, making
sure that signal loops don't occur.
• Filtering done for VLAN integrity - The switch filters packets from a member of a VLAN
(VLAN 2, for example) destined for a device on another VLAN (VLAN 3).
You can also manually configure the switch to drop packets from specified IP addresses.
4.3.1
IP Address Filtering
When filtering by IP address, you have three options. You can have the switch drop the packet
based on whether the IP address appears:
• as the source
• as the destination
• in either the source or destination
The table can contain 32 entries, and two table entries are needed to configure a bi-directional
filter.
4.4
Forwarding
The switch maintains a forwarding table. This table contains the relationship between destination
MAC or IP addresses and the Ethernet port or gateway router the destination resides on. This
information is then used to forward packets. This reduces the traffic congestion on the network,
because packets, instead of being transmitted to all ports, are transmitted to the destination port
only. For example, if Port 1 receives a packet destined for a station on Port 2, the switch transmits
that packet through Port 2 only, and transmits nothing through the other ports. This process is
referred to as “learning” the network topology.
You can configure forwarding rules for the following:
•
•
•
•
MAC address aging
MAC address forwarding
IP address to a specified gateway
IP address to a specified MAC address

Layer 2 Switch Features
4.5
Broadcast and Multicast Storm Control
You can specify thresholds for broadcast or multicast traffic that will activate storm control. When
the threshold is exceeded, the switch drops the broadcast or multicast traffic. When traffic levels
drop below the threshold, the switch resumes forwarding the traffic again.
The thresholds are applied to all Ethernet ports and cannot be set for individual ports. The threshold
specifies in thousands, the number of broadcast or multicast packets per second a port can receive
before triggering a storm control response. The possible range is from 0 K to 255 K packets per
second. This threshold can be configured to apply to broadcast packets, to multicast packets, or to
both.
4.6
Link Aggregation
Link aggregation allows several ports to be grouped together so that they can act as a single port.
This is done to either increase the bandwidth of a network connection or to increase fault tolerance.
The group has the following assignments:
• Master port: This port is the Ethernet port with the lowest port number. All member ports are
configured to use its port settings and become members of its VLAN.
• Anchor port: This port is in charge of sending control packets, such as spanning tree BPDUs,
and the flooding of multicast frames. When a link change event occurs in the group, the anchor
port may be re-elected.
When a link aggregation group is deleted or disabled, the ports retain their reassigned port settings.
They do not recover their original port settings. For example, suppose that Port 1 belongs to
VLAN1 and Port 2 belongs to VLAN2. When you create a group with a starting point of Port 1 and
a width of 2, Port 2 will be added to VLAN1 and removed from VLAN2 automatically. If you
delete or disable the group later, the Port 2 will still be assigned to VLAN1.
Remember the following guidelines when creating a link aggregation group:
•
•
•
•
•
4.7
Up to six groups can be established.
A group can contain up to eight ports.
Member ports of a group should always be the same speed and configured in full duplex mode.
You cannot create a group that includes 10/100 Ethernet ports and 100/1000 Ethernet ports.
STP will use the port parameters of the master port in the calculation of port cost and in
determining the state of the link aggregation group. The following formula is used to calculate
the path cost—group path cost = (path cost of master port) minus (number of ports in the
group).
Class of Service Support (CoS)
MAC address priority is a Layer 2 Class of Service. It allows certain frames, based on their MAC
address, to receive special handling. The following sections explain how this is done.

Intel® NetStructureTM ZT 8101 10/100 Ethernet Switch Technical Product Specification
Layer 2 Switch Features
4.7.1
MAC Address Priority
The frames can be prioritized based on whether the MAC address appears in:
• the source only
• the destination only
• both the source and destination
Frames that match the criteria are given a priority tag.
4.7.2
Priority Tags
The IEEE 802.1p specification defines a priority tag that is used to classify the frame’s forwarding
priority. There are eight levels of priority which range is from 0 – 7, with priority 7 as the highest
priority.
The switch supports only four hardware priority levels per port, so the eight levels are mapped to
four as listed in the table below.

Scheduling
After an Ethernet frame has been prioritized, the switch forwards the Ethernet frame using the strict
priority-based scheduling algorithm. With this policy, any packets residing in a higher priority
queue are always transmitted first. Only when these queues are empty are packets in lower priority
queues transmitted. This scheme can potentially starve packets in lower-priority queues.
Note:
If flow control is enabled, a small amount of low priority traffic may be forwarded before high
priority traffic.

VLAN Support
VLANs allow you to group some physical ports as if they were on the same LAN. VLANs can be
created either statically or dynamically:
• Static VLAN—This VLAN is manually configured on the switch.
• Dynamic VLAN—This VLAN uses GVRP (GARP VLAN Registration Protocol) to enable
ports to dynamically join a VLAN group.
VLANs reduce traffic because traffic between VLANs is restricted. Bridges forward unicast,
multicast, and broadcast traffic only on LAN segments that serve the VLAN to which the traffic
belongs.
The switch supports two kinds of VLANs:
• Port based VLAN—These VLANs are defined by the physical port connections to the switch
and are restricted to the number of ports in the switch. They use untagged frames.
• IEEE 802.1Q VLAN—These VLANS are based on a packet-tagging scheme. Packets may be
tagged or untagged. A tagged packet's membership in an 802.1Q VLAN is determined by a tag
that is inserted in the packet header by the switch or an end node indicating the VLAN number
that the packet belongs to. Untagged packets are treated as if they were in a port based VLAN,
where a connection to one of the switch's physical ports determines VLAN membership.
Physical ports can belong to only one VLAN as an untagged port, but can belong to more than
one 802.1Q VLAN as a tagged port. By default, all ports belong to a special VLAN called
“default”. This default VLAN is a IEEE 802.1Q VLAN, which has the following unique
characteristics:
— The name and the type fields are read-only.
— It cannot be deleted.
— It can contain no VLAN members.
— Its VID is 1, which cannot be changed.
All user-configured VLANs have the following characteristics:
• The size of VLAN name field is 32 bytes.
• Ingress checking is set to on.
• Up to 32 static VLANs can be configured.
The switch supports a maximum of 255 VLANs (64 static, the rest dynamic).

Layer 2 Switch Features
4.8.1
Static Port-Based VLANs
A port-based VLAN is the easiest type to configure on the switch because you need to specify only
the following:
• VLAN name
• Member ports
The complexity of the VLAN configuration is totally hidden. The switch applies the following
rules when it creates the VLAN:
• Tagged frames are discarded. With port-based VLANs, frames are assumed to be untagged, so
that the VLAN members do not receive frames coming from another VLAN.
• VLAN ID is assigned using an internal algorithm. The switch allocates the largest free VLAN
ID which is smaller than 4095 (for example, 4094, 4093, 4092).
• The member port’s PVID is assigned as the VLAN ID.
• A port can only belong to one port-based VLAN.
• Port-based VLANs are not included in GVRP advertisement.
4.8.2
Static IEEE 802.1Q VLANs
A static IEEE 802.1Q VLAN is more complex than a port-based VLAN, but it is also more
flexible. Tagged ports can belong to more than one VLAN. You can assign ports the following
attributes:
• Tagged Member Port: When a tagged member port sends a packet, the port changes the
packet header to include the 32-bit tag associated with the PVID (Port VLAN Identifier). If the
port is attached to a device that is IEEE 802.1Q VLAN compliant, (VLAN-tag aware), the port
can be set to tagged.
• Untagged Member Port: When an untagged member port receives a tagged packet, the port
strips the tag and changes the packet to an untagged packet. If the port is attached to a device
that is not IEEE 802.1Q VLAN compliant (VLAN-tag unaware), the port should be set to
untagged.
• Forbidden Port: When configured as a forbidden port, the port is designated as not being a
member of the VLAN and prevents packets tagged with the VLAN’s VID from entering the
port.
• Non-member: This labels the port as not being a member of the VLAN.
You can also enable or disable the following per port for IEEE 802.1Q VLANs:
• GVRP
• Ingress Checking
GVRP must be enabled globally on the switch before individual ports can be enabled.
Intel® NetStructureTM ZT 8101 10/100 Ethernet Switch Technical Product Specification
21
Layer 2 Switch Features
4.8.3
Global GVRP Settings
The global GVRP flag determines whether GVRP (Group VLAN Registration Protocol) is enabled
on the switch so that the switch can share VLAN information with other switches, and VLANs can
span multiple switches. When this flag is disabled, VLANs are confined to the physical
connections of the switch. By default, this flag is disabled.
GVRP uses the following settings, and they are not configurable:
• Join timer—200 ms
• Leave timer—600 ms
• Leave all timer—10 seconds
4.8.4
Ingress Checking
Ingress checking conditions the forwarding service for an Ethernet port. It has two states:
• Off: If an Ethernet port is configured with ingress checking off, all incoming tagged frames
are forwarded, even when the receiving port is not a member of the destination VLAN of the
frame.
• On: If an Ethernet port is configured with ingress checking on, all incoming tagged frames are
not forwarded. If the VID in the tagged frame belongs to the VLAN ID set, the frame is
forwarded; otherwise the frame is dropped.
The following table summarizes the conditions for forwarding tagged frames.

GMRP
GMRP (Group Multicast Registration Protocol) allows ports to dynamically join multicast groups.
It provides a mechanism that allows bridges and end-stations to dynamically register (and
subsequently, de-register) group membership information with the MAC bridge attached to the
same LAN segment. It also provides a mechanism for that information to be disseminated across
all bridges in the bridged LANs that support extended filtering services. The operation of GMRP
relies upon the services provided by GARP (Generic Attribute Registration Protocol).
In Release II, the switch will have a global flag to configure the GMRP protocol status for the
switch, and its default value will be disabled. The global setting will need to be enabled before
individual ports can be enabled. Once enabled, each individual port can be configured to
participate in GMRP or not.
The switch will have the following restrictions on members:
• The maximum number of static entries will be 32.
• The maximum number of dynamic entries will be 64.

Spanning Tree Protocol (IEEE 802.1D)
The Spanning Tree Protocol (STP) prevents loops in a network by allowing only one active path
between any two network devices at a time. STP operates on two levels. The switch has a global
setting, which either enables all ports to participate in STP or prevents all ports from participating
in STP. When STP is globally enabled on the switch, STP can be enabled and disabled on
individual ports.
4.10.1
Forwarding Database (Layer 2 Address Table)
The Layer 2 MAC forwarding database contains at most 8 KByte of entries (over 8,000 addresses).
The default aging time for dynamically learned entries is 300 seconds. The value is userconfigurable; the range is 300 to 1,000,000 seconds. The switch has a minimum learning rate of 3K
MAC addresses per second.
When the switch discovers that a topology change has occurred, the STP aging time is decreased to
the “Forward Delay” time, which has a default value of 15 seconds. (The default STP aging time is
20 seconds.)
The forwarding database supports two types of static entries: static and black hole.
• Black Hole: If a black-hole entry is added for a specified MAC address, the switch discards all
frames with the specified MAC address in the source or destination field.
• Static: If a static entry is added for a MAC address, the switch forwards all frames with this
MAC address to a specified port.
4.10.2
Path Cost Issue
When you enable STP and you do not configure a port cost for a port, the switch assigns a default
port cost based on the port’s current link speed.
Table 5.

For the master port of the group, the path cost is the assigned value minus the number of ports in
the group. However, if you configure the path cost for the master port, the configured value will be
used instead.

Security
For increased security, the switch supports restricting management access to a specified list of IP
addresses. The management station IP address is composed of an IP address and an Ethernet port
number. This list determines which stations can request authentication to the switch through the
SNMP, Telnet, and Web interfaces. For the request to be considered, the station’s IP address must
match one in the list. If no addresses are entered into the list, any station can request authentication
to the switch. SNMP then uses community strings to control access. The Telnet and Web interfaces
use user accounts to enforce security.
5.2
IP Interfaces
An IP interface associates an IP address with a specific VLAN, which allows the VLAN to act as
Layer 3 and be configured for RIP and multicasting protocols. Each VLAN must be configured
prior to setting up the corresponding IP interface. An IP addressing scheme must then be
established and implemented when the IP interfaces are set up on the switch.
5.2.1
System IP Interface
The switch is shipped with one pre-configured IP interface called System. This name cannot be
modified. By default, the System IP interface is bound to the default VLAN (VID=1). This VLAN
contains all the switch’s Ethernet ports.
You can assign or change the IP address of the System IP interface with a manual assignment,
BOOP, or DHCP. The switch uses the IP address assigned to the switch as the IP address for the
System IP interface.
Note:
5.2.2
BOOTP and DHCP are only available for the System IP interface.
Additional IP Interfaces
To add an IP interface to the switch, you must first configure a VLAN and then associate an IP
address (subnet mask and gateway) with the VLAN.
Note:
The switch must have a manually assigned IP address in order to configure additional IP interfaces.
User defined IP interfaces differ from the System IP interface in the following ways:
• They cannot use BOOTP/DHCP to get a dynamic IP address. They must be assigned a manual
IP address.
• They can be renamed. However, when the change is applied, all other settings for the IP
interface are changed to their default values. This includes the settings for RIP and the IP
multicast protocols.

TFTP Client
TFTP is a simple protocol used to transfer files without any kind of authentication. It runs on top of
UDP, using timeout and retransmission to ensure that data arrives. The switch’s TFTP client allows
users to copy files from and to a remote system that is running the TFTP server protocol. The TFTP
client allows only one user to access it and transfer files.
You can use the TFTP client is to do the following:
• Download firmware.
• Download and upload the switch’s configuration file.
• Upload the switch’s history log.
Note:
5.5
Some TFTP servers cannot determine when a transaction is aborted. In these cases, you must
reboot the switch, which restarts the TFTP client and re-initializes the TFTP transaction.
Ping
The Ping utility invokes the ICMP echo request and echo reply messages. A host or gateway sends
an ICMP echo request message to a specified destination. Any machine that receives an echo
request formulates an echo reply and transmits it to the original sender. The echo request and
associated reply can be used to test whether a destination is reachable and responding.
When handling a subnet-broadcast or a directed-broadcast ICMP echo request, the switch forwards
the subnet-broadcast or directed-broadcast ICMP echo request to the destination network.

ARP Table
The ARP table maintains the mappings from Internet addresses to hardware addresses. There are
two types of ARP entries: dynamic and static.
When a static ARP entry is added to the switch’s ARP table, the switch does not send an ARP
query to the configured IP address. This allows the switch to connect to devices that have not
implemented ARP.
The ARP table has the following characteristics:
• Static entries have higher precedence than dynamic entries. Therefore, a static entry will not be
overwritten by a dynamic entry.
• The aging time for dynamic entries is 20 minutes. This value is not configurable.
• The table can be up to 2 K in size.
• Up to 32 static entries are allowed in the table.
6.2
Routing Table
TCP/IP routing protocols have ways of discovering the reachable IP address prefixes and, for each
prefix, the next-hop router to use to forward data traffic to the prefix. The information exchanged
between routers results in an internal database called the routing table, which instructs the router
how to forward packets. There are two common implementations for a router’s routing table: hash
+ binary tree algorithm and Patricia tree. Both algorithms have their strengths and weaknesses.
Since Layer 3 software is currently configured to use the Patricia tree algorithm, the ZT 8101
switch uses the Patricia tree algorithm.
The switch’s routing table has the following characteristics:
• The table can be up to 2 K in size.
• Up to 32 static entries are allowed in the table.
6.3
Multi-Netting
In legacy networks, multi-netting is commonly used to configure a physical router port with more
than one IP interface. In a Layer 3 switch, an IP interface is bound to a single VLAN. To
accommodate multi-netting, you must configure two or more tagged VLANs to span the same
physical ports and then assign each VLAN a different IP address.
The VLANs must include tagged ports, because untagged ports can only belong to one VLAN.

The ZT 8101 switch supports both DVMRP and PIM-DM, and both protocols can be enabled at the

7.1
Router Ports
When the switch detects routing control packets (RIP, OSPF, DVMRP, and PIM) or IGMP query
packets on an Ethernet port of a specific VLAN, the switch automatically designates the port as a
dynamic router port. Router ports become default members of the learned multicast groups in the
VLAN.
The switch allows you to configure ports as static router ports. These ports also become default
members of the learned multicast groups in the VLAN.
7.2
Multicast Forwarding Rules
The forwarding rules depend upon whether the packets need to be forwarded within a VLAN or
between VLANs. The following sections describe these rules.
7.2.1

Multicast Forwarding between VLANs
When a multicast routing protocol is enabled, such as DVMRP or PIM, the multicast data can be
forwarded to other IP interfaces, if needed. Either software or hardware can be used to forward an
IP multicast packet. The switch currently supports software forwarding.
7.2.2.1
Software Forwarding
To improve switch performance, IP multicast packets are flooded to the VLAN domain and are not
sent to switch’s CPU. When you enable any multicast routing protocol (DVMRP or PIM-DM), all
of the IP multicast packets are sent to switch’s CPU to do further forwarding processing.
An internal multicast forwarding cache is used to match an incoming IP multicast packet with a
forwarding IP interface. The multicast forwarding cache contains the following information:
• The sender’s source IP address
• The sender’s multicast group IP address
• A bitmap of forwarding IP interfaces
The multicast group IP address is used as the table’s index.
When the switch receives an IP multicast packet, it either builds or updates the internal multicast
forwarding cache. The relevant bit in the forwarding bitmap is updated according to the results of
multicast routing protocol exchanges and IGMP reports.
The following tables describe the forwarding rules for multicast data.

IGMP Queries
An IGMP querier sends IGMP Query packets periodically to help to maintain the multicast group
information for a VLAN. When IGMP Snooping is enabled for a VLAN, the switch uses the
following states to determine whether the VLAN becomes a querier:
• Non-Querier: Prevents the VLAN from becoming a querier.
• V1 Querier: Enables the sending of IGMPv1 query packets. If no querier is present in the
VLAN or the VLAN’s IP address is smaller than current V1 querier, the switch becomes the
querier for the VLAN. IGMPv2 group specific query and leave packets are not handled.
• V2 Querier: If a V1 querier is present in the VLAN, the switch remains silent. If no querier is
present in the VLAN or the VLAN’s IP address is smaller than current V2 querier, the switch
becomes the querier for the VLAN. IGMPv2 group specific query and leave packets are
handled.
When receiving an IGMPv2 leave packet, the IGMP interface issues an IGMPv2 group
specific query packet immediately and waits one second to check if any IGMP reports are
received on the ports. If not, the port is removed from the IGMP group member list, and the
group's multicast data is not forwarded to this port until an IGMP report is received again.
The outgoing ports for the IGMPv1 Query or IGMPv2 Query packets are defined in Multicast
Forwarding within a VLAN section.
If the IGMP interface is designated as the IGMP querier, the switch uses the following intervals for
sending query packets:
• When you enable IGMP snooping or boot the switch with the querier option enabled, the first
query packet will not be sent for 255 seconds. This time delay is non-standard.
• The second query packet will be sent after the “Startup Querier Interval” which is 1/4 *
“Query Interval.” By default, this is 31 seconds.
• The next query packets will be sent periodically according to the “Query Interval.” The default
“Query Interval” is 125 seconds.
The following table gives the sequence of these packets.

IGMP Snooping
IGMP Snooping is a feature that reduces the flooding of IP multicast traffic.The default behavior
for handling a multicast packet is to flood the packet to all members of a VLAN. With IGMP
Snooping, only the active member ports receive the data.
All groups learned by IGMP snooping are recorded in an internal group table with the VLAN ID
and multicast group address used as the table’s index. This table stores the active member ports for
this group. This table can contain a maximum of 128 groups. If the active multicast groups exceed
this limit, the new group’s data will be flooded in the VLAN.
You can globally enable or disable IGMP Snooping on the switch. You can also enable or disable
the snooping for a specific VLAN. You must enable IGMP globally for it to be enabled on a
specific VLAN. By default, the IGMP global flag is off and per-VLAN flag is on. Thus, when you
enable IGMP globally, it is enabled on all VLANs.
You can configure the switch to snoop and to keep track of IGMP groups. These two interact in the
following ways:
• If the IP interface has IGMP Snooping configured for the associated VLAN, the configuration
of IGMP Snooping will be overwritten by the IGMP group settings. On such VLANs, the perVLAN flag is the only available configurable option on the IGMP Snooping screen.
• If the IGMP group settings are disabled on the interface, IGMP Snooping on the VLAN
becomes configurable and the switch uses these settings for the VLAN.
Note:
36
The switch supports a maximum of 255 VLANs and a maximum of 128 IGMP Snooping groups. If
you create more than 128 VLANs with IGMP Snooping enabled, some of those VLANs will not be
added to the IGMP Snooping table and the group’s data will be flooded in the VLAN.

7.5
IGMP Group Settings
An IP host uses IGMP to register its IP multicast group membership with the switch. Periodically,
the switch queries the multicast group to see if the group is still in use:
• If the group is still active, a single IP host responds to the query, and the group registration is
maintained.
• If the group is inactive and a report is not received within the time limit for a response, the
group registration is removed.
7.6
DVMRP
DVMRP is a distance-vector routing protocol designed to support the forwarding of multicast
datagrams through an inter-network. DVMRP constructs source-rooted multicast delivery trees
using the Reverse Path Multicasting (RPM) algorithm. Unlike RIP, DVMRP is concerned with
computing the previous hops back to a source. The ZT 8101 switch supports DVMRP v3.
7.7
PIM Dense Mode (PIM-DM)
PIM Dense Mode (PIM-DM) is similar to DVMRP in that it employs the Reverse Path
Multicasting (RPM) algorithm. However, there are several important differences between PIM-DM
and DVMRP:
• PIM-DM relies on the presence of an existing unicast routing protocol to adapt to topology
changes, but it is independent of the mechanisms of the specific unicast routing protocol. In
contrast, DVMRP contains an integrated routing protocol that makes use of its own RIP-like
exchanges to compute the required unicast routing information.
• Unlike DVMRP, which calculates a set of child interfaces for each (source and group) pair,
PIM-DM simply forwards multicast traffic on all downstream interfaces until explicit prune
messages are received. PIM-DM is willing to accept packet duplication to eliminate routing
protocol dependencies and to avoid the overhead involved in building the parent/child
database.
The ZT 8101 switch supports PIM-DM v2.

Firmware Upgrade
8.6.1
Upgrade Runtime through TFTP
To upgrade the switch’s firmware, you must first complete the following tasks:
• You must obtain an updated runtime version of the firmware.
• You must copy the firmware to a known directory on a TFTP server.
Once the firmware is on the TFTP server, you can upgrade the switch from the serial, Telnet, or
Web interface. Only one TFTP upgrade session is allowed at a time. When the download has
completed and the firmware has been written to flash, the switch will automatically reboot and
execute the new runtime firmware.

8.6.2
Upgrade Runtime through Zmodem
Generally, TFTP is the first choice to use to upgrade firmware. The Telnet Console and the Web
Console both have options for upgrading the firmware using a TFTP server. However, you can also
use Zmodem to upgrade the firmware from the serial port. The switch can hold only one image of
the firmware.
8.6.2.1
To upgrade the firmware using Zmodem
1. Obtain the runtime firmware.
2. Using Windows HyperTerminal, log in to the switch through the serial port.
3. From the Main Menu, select Reboot and press Enter.
4. When the power on self test message appears, press the # key and wait for the following
message:
Please change your baud rate to 115200 for the Zmodem upgrade, or
press CTRL+C to go to the BOOT Menu.
If you press CTRL-C, you can configure the baud rate to a different value.
5. Change HyperTerminal’s baud rate to match the target’s setting.
6. Use the Send File function of HyperTerminal to upgrade the firmware.
When the download is completed, Zmodem will display a message indicating that it is done
and then a message about loading the Runtime image.
7. Change the baud rate of HyperTerminal back to 9600 bps.
8. Press the Enter key twice.
9. Log in to the switch.
10. From the main menu, select Switch Information and press Enter. Verify the firmware version.

CompactPCI
The ZT 8101 switch complies with PICMG 2.1 Hot Swap specification for insertion and removal
of the ZT 8101 board.
The ZT 8101 slot in the chassis will have the BD_SEL# pin grounded. When the ZT 8101 switch is
inserted, the hot swap power controller will wait until BD_SEL# is grounded and backplane power
has stabilized before ramping up main power to ZT 8101. If backplane power becomes unstable or
BD_SEL# goes high, the hot swap power controller will turn off main power to the ZT 8101
switch.
A CPLD is used to control the hot swap LED, and reset to the board. See the Hot Swap section for
details on the hot swap logic.
The blue LED will be on at any time it is safe to remove the ZT 8101 switch.
9.5
Power Controller
The hot swap power controller chip is used to ramp voltages and watch for over current. If over
current is detected, main power to the ZT 8101 switch will be terminated. Over current is defined
as 50 percent over spec.
A time constant of 100uS is used on startup to prevent any surges.
The ZT 8101 switch has a Hot Swap Shield on the back of the board to protect the circuits.
The hot swap power controller chip is a LTC1421 chip.
9.6
Regulators
The ZT 8101 switch generates the on board voltages from both 3.3 V and 5 V.
A switching regulator generates 2.5 V (for two Octal Phy) and 1.8 V (switch engine) from the 5 V.
Several LDO regulators generate the 2.5 V needed for the CPU core, 10/100/1000 and Octal Phy.
The switching regulator is a RT-9226B. The 2.5 V LDO regulator is a CS-5253.
9.7
Embedded Controller
The ZT 8101 switch uses the TX-3927 RISC CPU.
9.8
Ethernet
The ZT 8101 switch utilizes a single chip Ethernet switch controller solution that has 24 10/100
ports and 2 GbE ports.

Intel® NetStructureTM ZT 8101 10/100 Ethernet Switch Technical Product Specification
Hardware
9.12
Watchdog
The switch uses a TX3927 internal watchdog timer and one external watchdog timer inside CPLD.
9.13
Clocks
There are four clock sources:
• 25 MHz for GbE PHY chips
• 125 MHz for switch controller core frequency, Octal PHY SMII clock and GbE PHY GMII
clock
• 100 MHz for SDRAM clock
• 8.33 MHz for TX3927.
All of them are generated from oscillator.
9.14
Front Panel
The front panel of the ZT 8101 switch has the following items.
Table 30. Front Panel Items
Item
Description
Ejector switch
This switch tells the hot swap controller if the user wants to remove the
card. While this switch is closed, the card cannot physically be removed.
Hot Swap LED
This blue LED tells the user it is safe to remove the ZT 8101 switch. If this
LED is not on, damage to the chassis, the ZT 8101 switch, or modules in
the chassis could result by removing the ZT 8101 switch.
RJ-45 Ports
There are 4 RJ-45 ports. Two of them are for 10BASE-T/100BASE-TX
Ethernet ports and two of them are for 100BASE-TX/1000BASE-T
Ethernet ports.
Board Status LED
The status LED shows the health of the board and its power state.
Management Serial Port
The serial port allows the user to attach a terminal or a PC running
terminal emulation software (such as HyperTerminal) and manage the
switch.
Ethernet Channel LEDs
These LEDs indicate either the activity or the speed of the ports.

Hardware
9.15
Hot Swap
The blue hot swap LED has controlled ejector switch logic, which is powered by early power and
the CPLD. A 3.3 V high signal from the CPLD means to turn on the LED. Since a blue LED
requires a large forward voltage, it uses the following circuit to drive the blue LED.
Figure 5. Hot Swap LED
5V
HSR
A PIO pin is used to indicate that the ejector latch of the switch has been opened. When the user
opens the ejector latch of the switch, the PIO pin is pulled low to inform the CPU that hot swap is
in progress. When the switch’s polling task notices this event, it forces each port into link down
mode and then lights a LED to indicate that it is safe to unplug the switch.
9.16

• Over temperature
• Exceeding voltage limits
• IPMB time outs

Ethernet Channel LEDs
The LED array on the front panel displays information about all the Ethernet links on the board. A
green/amber two-color LED is used for each of the 26 Ethernet port connections (24 10/100 + 2
Gigabit). A push button switch just below the array toggles the LED display from Link /Activity
mode to Link / Speed mode. The default LED mode is Link /Activity. When the switch button is
depressed, the LEDs are in Link/Speed mode.

Fast Filter Processor
The ZT 8101 supports an extensive filtering mechanism and packet classification, which enables a
switch application to filter and classify based on certain protocol fields in the packet. You can also
filter on specified ingress or egress ports.
Filtering uses two constructs:
• The filter mask defines which fields to filter.
• The rule table defines the filtering options.
11.2
MARL Table
The MARL table is used to limit the flooding domain for a specific multicast MAC address. The
table size is 256, but one entry is reserved by ASIC. Both IGMP snooping and GMRP use this

Precaución: Requisitos de entorno para el sistema: Los componentes del tipo de placas de
procesador, conmutadores de Ethernet, etc., están concebidos para funcionar en condiciones que
permitan el paso de aire. Los componentes pueden averiarse si funcionan sin que circule el aire en
su entorno. La circulación del aire suele estar facilitada por los ventiladores incorporados en el
armazón cuando los componentes están instalados en armazones compatibles. Nunca interrumpa el
paso del aire por los ventiladores or los respiraderos. Los paneles de relleno y las placas para el
control de la circulación del aire deben instalarse en ranuras del chasis que no estén destinadas a
ningún otro uso. Las características técnicas relativas al entorno pueden variar entre productos.
Consulte los manuales de usuario del producto si necesita conocer sus necesidades en términos de
circulación de aire u otras características técnicas.
Advertencia: En condiciones de funcionamiento normales, los disipadores de calor pueden
recalentarse. Evite que ningún elemento entre en contacto con los disipadores para evitar
quemaduras.
Advertencia: Riesgos de daños, incendio o explosión: No permita que el aparato funcione en una
atmósfera que presente riesgos de explosión.
Precaución: El usuario no debe cambiar las baterías de litio. Si las baterías no se manipulan o
cambian correctamente, exite riesgo de explosión. No desmonte ni recargue la batería. Nunca tire
las baterías al fuego. Al cambiar la batería, es preciso utilizar el mismo tipo o un tipo equivalente
que haya sido recomendado por el fabricante. Las baterías utilizadas deben desecharse según las
instrucciones del fabricante. Devuelva la unidad a Intel si la batería necesita algún tipo de
operación de mantenimiento.
Advertencia: Daños personales: Este producto puede contener uno o varios dispositivos láser,
